DOWNEY prefixes in area code 562
NANPA records 77 assigned NXX blocks to rate center DOWNEY in area code 562, 11.0% of the 702 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 19 holders hold those blocks, the largest being T-MOBILE USA, INC. (15), FRONTIER CALIFORNIA INC. (15), METROPCS NETWORKS, LLC (10). The earliest assignment on record here is 2001-01-16 and the most recent 2026-07-09. 64 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
